COMBINED DlRT ROLLER AND PULVERIZER.

SPECIFICATION forming part of Letters Patent No. 6( )5 ,I60, dated une 7, 1898.

Application filed May 23, 1896.

Be it known that L LAnsnonn CHAMBERS,

a citizen of the United statcspresidingat Bartlett, in the county of Fremont and State of Iowa, have invented a new'and useful Oombined Dirt Roller andPulveri'zer, of which the following is a specification.

My invention relates to a new and improved ner as to crush clods, tear up and pulverizethe ground by loosening it up when reversed and when thrown in opposite direction to smooth the same.

The objects of my invention are, first, to pulverize and crush the soil as the'rollers revolve on the ground in one direction by pushing back the dirt and pulling up and destroying all vegetation, making the ground mellow and freeing it from clods instead of crushing them into the ground; as a simple roller would do; second, whe the rollers are reversed (the clods having been pulverized by the use of the pulverizer) they operate to make the ground smooth and level, and when used on ground planted with corn or small grain it is left in good shape for the use of the cultivator. "I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a top plan of the entire machine. Fig. 2 is a longitudinal section of the tongue and frame; Fig. 3, a view of the seat attached to the steel spring, by which the same is at-- tached to the frame, as shown inFig. 1. Fig. 4 is a perspective of one of the cylindrical Fig. 5 isthe shaft which passes through the roller and is attached to each end and to the frame, asshown in Fig. 1. Fig. 6 is a detail of the iron lubricating-box, in which the two shafts rest in the center of the machine, as shown in Fig. 2; and Fig. 7 is adetail of the single boxes attached to the frame at the outer ends of the shaft.

Similar letters on the drawings refer to similar parts of the machine throughout the views.

As shown in Fig. 1, the framework 0 of the machine is composed of two wooden bars at Serial No. 592,893. (No a.)

right angles to the tongue and located one behind the other and connected at their ends "and center by shorter bars, which comprise a rectangular frame adapted to receive the two rollers, as clearly shown in Fig. 1. The rollers are attached to the'frame at each of the outer Tends by the single boxes, Fig. 7, and in the middle by a double lubricatingbox, Fig. 6, each'of which is securely bolted to the frame 0. The rollers'are attached to the frame by means of the shaft passing through the rollers and resting in the boxes. To the frame 0 is secured the tongue A, and bolted to the frame and tongue are two iron braces B B for the purpose of holding said tongue securely in place and strengthening the attachment of said tongue to the machine. The cylindrical rollers are made of cast-iron and provided with concaved flutes H one and three-fourths inches deep, four inches between eachflute, and fourteen flutes in each roller. The rollers when attached to the machine for use are about six inches apart the drawings. The'steel spring by which the piece of spring-steel bent for the purpose of forming a support to the drivers seat. The two rollers are reversed by unboltin g the boxing at eachend'of the roller and'turning them half around or changing the ends'of the shaft through the rollers in the boxing. The rollers are securely keyed to the shaft and held from revolving thereon.

, Having describedlmyinvention, WhatI now claim, anddesire to secure by Letters Patout, is-- A combined land roller and pulverizer comprising a cylindrical body or bodies, the surface of which is fluted, thereby forminglongitudinal crushing blades or bars arranged tangentially mounted in a suitable supportingframe provided with a draft device whereby when the roller is drawn in one direction the soil is cut and pulverized, and in the reverse direction the soil is smoothed, substantially as described.
